P2119 2003 Toyota Highlander Code - Throttle Actuator Control Throttle Body Range/Performance
Quick Answer
The Electric Throttle Control System (ETCS) is composed of the throttle motor to operate the throttle valve, the electromagnetic clutch to connect the throttle motor with the throttle valve, the throttle position sensor to detect the opening angle of the throttle valve, the accelerator pedal position sensor to detect the accelerator pedal position, the ECM to control the ETCS and the one valve type throttle body. Common causes include Faulty electric throttle control actuator, Throttle plate sticking due to carbon build-up, Electric throttle control actuator harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2119 2003 Toyota Highlander Description
The ECM controls the throttle motor to make the throttle valve opening angle properly in response driving condition.
The throttle position sensor which is mounted on the throttle body detects the opening angle of the throttle valve, and it provides feedback to the ECM to control the throttle motor.
If the ETCS has a malfunction, the ECM shuts down the power for the throttle motor and the magnetic clutch, and the throttle valve is fully closed by the return spring.
However, the opening angle of the throttle valve can be controlled by the accelerator pedal through the throttle cable.

- Faulty electric throttle control actuator
- Throttle plate sticking due to carbon build-up
- Electric throttle control actuator harness is open or shorted
- Electric throttle control actuator poor electrical circuit connection
- Engine Control Module
